02 grand 4.0l
99 xj 4.0l
beside the oil question are both these engines the same or do they have different heads or other different parts? the only noticable thing i see is one has a manaul belt tensioner and one is automatic.
it looks like mobil 1 and Rotella seem to have the most zinc that we look for according to what i have been reading but does the Rotella T5 synthetic "blend" (not full) have more or less than the regular T or T3 and does the mobil 1 high mileage have more or less than both of those?? all in 10w-30. I use to use the Mobil 1 high mileage and switched to the castrol high mileage. I use a wix filter also . when i bought this about 2 years ago I had the flappy, ticking slappy noise that was on start up and was trying a few didnt brands to see if it changed it . the castrol high mileage i rarely hear it now with the cold weather or cold start ups. this rotella id like to try. what do you guys know about the zinc levels and have you had any experience with the Rotella vs the mobil 1 HM even the castrol HM????????? thanks
